Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 32

A minimal faithful permutation representation — 4 generators on 24 points:

(2,5)(3,7)(6,8)(14,20)(21,24);(1,2,4,6)(3,8,7,5)(9,10)(11,14)(12,15)(13,16)(17,21)(18,20)(19,22)(23,24);(9,11)(10,14)(12,17)(13,18)(15,21)(16,20)(19,23)(22,24);(9,12,13,19)(10,15,16,22)(11,17,18,23)(14,21,20,24)
